VAMP Ltd.’s Vamp 221 is a dual-sensing and multi-zone arc
protection system for low and medium voltage electrical power safety
applications. The system’s ability to trip in just seven milliseconds means
that electrical arcs are stopped well before their full explosive potential is
reached, according to the company. Vamp 221 uses light and current sensing
information to provide faster and more efficient protection than standalone
over-current relays or busbar differential schemes, Vamp says. The master 221 module
comes with 3-phase current measurement, 50BF breaker failure protection stages,
four normally open trip contacts and two alarm contacts. Vamp says it can be
programmed to sense electric arc conditions using either simultaneous light and
current data, or light sensor information only. www.vamp.fi
